A marble dropped from a bridge strikes the water in 5 seconds. What is the speed with which it strikes and the height of the bridge?
Velocity final = vi + at = 49 m/s displacement = vi * t + ½2at² = 122.5 m vi = 0 a ≈ 9.8 t = 5
Why do you have to multiply the average speed of a ball going down a ramp by 2 in order to find its final speed?
The last moment, the speed is the final, the first moment, the speed is zero, average=final /2. For the bit just before the final, and the bit an equal bit just after the start the average is again final/2. For every instant before the final, coupled with the same instant after the start, the average is final/2. So the average for the whole trip is final/2. So to get the final, multiply the average by 2.
Is final velocity equal to speed?
Yea it is.
If a small marble is dropped straight downward what is the initial velocity of the marble?
The initial velocity is zero. In most basic physics problems like this one the initial velocity will be zero as a rule of thumb: the initial velocity is always zero, unless otherwise stated, or this is what you are solving for Cases where the initial velocity is not zero examples a cannon ball is shot out of a cannon at 50 mph a ball is thrown from at a speed of 15 mph etc
What is vertical speed?
Vertial Speed is final depth minus intitial depth divided by time
Is instantaneous speed final speed?
No instantaneous speed is not final speed.
It takes 6 seconds for a stone dropped from rest to hit the bottom of a well what is its final speed?
60 m/s
A can rolled down an incline and accelerated at a uniform rate It started from rest a speed of 0 ms and reached the bottom of the incline moving with a speed of 1.8ms state the average speed?
For uniform acceleration the average speed is the initial speed plus the final speed divided by two.
What is the top speed of a v8 supercar?
The fastest they get up to is at the bottom of the Conrod Straight at Bathurst. They top out at about 180mph (300kph) before slamming on for the Chase.
If a car is speeding up its initial speed is what than its final speed?
Its initial speed is less than its final speed.
If a car is traveling at a constant speed of 60 miles per hour for 30 minutes what is the acceleration?
Constant speed (in a straight line) means there is no acceleration.Constant speed (in a straight line) means there is no acceleration.Constant speed (in a straight line) means there is no acceleration.Constant speed (in a straight line) means there is no acceleration.
What causes a marble to reach the groud first if a feather and the marble accelerate at the same speed?
A marble is more dense and has less surface area, so it is not affected by air resistance as much as the feather.
How is constant speed shown on a graph?
Constant speed is shown on a graph using straight lines. The straight line indicates that there are no fluctuations with the speed.
Does the height of a ramp affect the speed of a marble?
Yes.The higher the ramp the faster.
How will the angle of the ramp affect the speed of the marble?
if its steeper it'll go faster
What is the motion of a marble when an unbalanced force influences it?
An unbalanced force can cause the marble to start moving, stop moving, change its speed or change its direction.
What is the acceleration of car that travels in a straight line at constant speed?
Straight line at a constant speed = no acceleration
